SAS H-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 230,434, dated July 27, 1880.

Application filed May 1, 1880. ModeL) Patented in Canada March 30, 1880.

To all whom it may concern Be itknown that I, JOHN PAYNE, of New Hamburg, in the county of Waterloo, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Sash- Fasteners; 'and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to an improvement in sash-fasteners of that class having a pinionwheel engaging with a rack-bar on the sash or the window-casing; and the object of the invention is to lock the pinion by two overturning pawls, whereby the pinion revolves past one of them in one direction and not in the other to lock the sash when open or closed, or to arrest it from falling when partly raised; and my invention consists of an open castmetal frame having two sides, between which the pinion-wheel and pawls are journaled on holding-screws, which secure said frame in position. The two pawls are hung at the upper extremity of the frame to gravitate in engagement with the pinion, said pawls having a turnover movement one upon the other, to cause one or both pawls to engage with the pinion to lock the sash, as above described.

Figure 1 is a front elevation of the upper sash, with fastener of modified construction. Fig. 2 is a side elevation of the lower sash with my improved fastener. Figs. 3 and 4 are side views of the fasteners shown in Figs. 1 and 2, respectively.

A is the sash; B, a rack-bar secured to the sash, as in Fig. 2, or window-casing, as shown in Fig. 1.

O is an open metal frame, having two side bars connected by anintervening bar or bars, whereby the sides are kept rigidly apart and to allow the frame to be cast integrally.

D is a pinion-wheel journaled between the sides of the frame A upon a holding-screw passing through the sides of the frame A, and which screw also serves to fix the frame to the sash or casing in such a position that the pinion will engage with the rack-bar B..

F F are two pawls hung on a pin or holdingscrew passing through the upper extremity of the metal frame 0 into the window-casing.

Both pawls are halved atthe pivot-hole, where- 0 by a shoulder is formed on the extremity which engages with the pinion D. The upper pawl, (shown in Fig. 2,) when in engagement with the pinion, prevents the sash beinglifted, and the lower pawl sustains the sash from falling. 5 When both pawls engage with the pinion the sash is held from movement either up or down when partly open.

When the upper pawl in Fig. 2 is overturned outwardly from the sash to lie on theback of the lower pawl, so as to be out of engagement with the pinion, the pinion will revolve past the lower pawl when raising the sash, but will be arrested by it when falling, and thus sustain the sash at any desired height.

When both pawls are engaged with the pinion, as shown in Fig. 2, the sash will belocked when open, so that it cannot be moved either up or down, and in like manner the sash will be locked from rising when closed by the-en- 7o gagement of the lower pawl, which must be overturned from engagement when the sash is being lowered. The pinion will then revolve past the upper pawl on the downwardv movement of the sash, and when closed is prevented from rising by the upper pawl taking effect.

The engagement of both pawls with the pinion is effected by gravitation, and each pawl hasa turn-over disengagement movement upon the other then in engagement with the pinion, whereby, when such change of engagement occurs, the pinion revolves past the one in engagement in one direction, but not in the other.

The pawls are provided with a projection, F, to facilitate manipulation by the fingers, as above described.

In Figs. 1 and 3 I show, as a modification,

a pawl corresponding to the two pawls F F if cast integrally back to back, with aturn-over adjustment, whereby the sash can be arrested 0 from falling or from being raised when open; but such pawl will not lock the sash immovably when open.

I am aware that it is not new to place the pinion on the sash and rack on the window- 5 casing, and vice versa, and I do not broadly claim such arrangement as my invention.

I claim as my invention- The combination, with a rack-bar, B, of a but not in the other, whereby the sash is imsash-fastener composed of the open frame 0, movably fixed when partly open, or arrested 10 pinion D, and two pawls, F F, hung at the from fallingor locked when closed by the adupper extremity of the frame to gravitate in jnstnient of the pawls, as set forth.
